Sailor Moon Crystal Act 14 is the start of the series’s second arc: Black Moon. This is equivalent to the 90s anime’s second season: Sailor Moon R. The Doom Tree Arc featuring the two aliens Al and En did not exist in the manga (it is exclusive to the 90s anime storyline) so it will be skipped in Sailor Moon Crystal. Following closely to its manga source, it will introduce Chibiusa as Sailor Chibi Moon and Sailor Pluto, the Guardian of Time!
